Variable density sampling with continuous trajectories. Application to MRI

Nicolas Chauffert, Philippe Ciuciu, Jonas Kahn +1

Reducing acquisition time is a crucial challenge for many imaging techniques. Compressed Sensing (CS) theory offers an appealing framework to address this issue since it provides t…

From variable density sampling to continuous sampling using Markov chains

Nicolas Chauffert, Philippe Ciuciu, Pierre Weiss +1

Since its discovery over the last decade, Compressed Sensing (CS) has been successfully applied to Magnetic Reso- nance Imaging (MRI). It has been shown to be a powerful way to red…

Travelling salesman-based variable density sampling

Nicolas Chauffert, Philippe Ciuciu, Jonas Kahn +1

Compressed sensing theory indicates that selecting a few measurements independently at random is a near optimal strategy to sense sparse or compressible signals. This is infeasible…
